Firehouse15 Posted April 21, 2009 Report Share Posted April 21, 2009 Should I be concerned?? Just purchased a 2003 996. When I run my 2003 996 to operating temp and idle it, it seems to have a noticeable ticking noise from the lower part drivers side of the motor. When cold it doesn’t make a noise only at operating temp. If I rev the engine it seems to go away until idle again. Could it be the exhaust system rattling or what could it be. The car runs strong……… Thanks. Gord. Link to comment Share on other sites More sharing options...
tortonness Posted June 2, 2009 Report Share Posted June 2, 2009 i noticed the same ting on my 99 modell 996 c4. when i idles there is a ticking sound but when i rev it a bit it goes away and the car pulls strong when i drive it.it sounds like its comming from the exhaust. It might be the valves. the car has been in storage for the winter so i might be that it just needs to be driven a bit. Link to comment Share on other sites More sharing options...
